Bar of Copper is a type of metal acquired from Mining and Smelting Metal Ores using buildings such as an Ore Smelter, Crucible, or Finery Forge. Due to the inherent dangers of mining and relative scarcity of ore, all types of metal are highly sought after. A Bar of Copper can be used to craft any tool or building requiring a Bar of Common Metal.

A Bar of Copper is one of the least valuable metals due to its lack of crafting recipes, availability, and generally low quality, but is equally important in crafting Bronze

Next, the ore must be loaded into an Ore Smelter. At least twelve units of Coal or Black Coal must be added to the smelter by right-clicking on it, while holding a unit of coal on the cursor. Finally, use a Firebrand or Torch to light the smelter.

After roughly 50 minutes, the process will be complete. The percentage of ore to bars will be directly resultant of the type of ore smelted, modified by whether you possess any additional mining skills. Any ore that does not become a bar will become Gneiss.
